I don't know why this would be happening but when I use a PivotGrid, it interrupts or distorts the RadMenu CSS (see images attached). Below is the mark up for the page. This is in IE11, Telerik v.2015.2.729.45.
Please do not advise that I upgrade, I do not have the funds, but I would appreciate a work-around.
